Populated Fields from Discovery

[IS8891]

hi guys i need help with the below question. can anyone suggest me the process to collect the data required.

what data is being populated by discovery and what fields this data goes into. Idea is to be able to provide this document to users to explain where the data is populated.

Hi,

In Discovery, the probe is fired which fetch or collect data from IP enabled devices and sensor process that data that is Sensor decides where to populate that data.

Consider an example of windows discovery, the data populated from this is mention in below link.

https://docs.servicenow.com/bundle/jakarta-it-operations-management/page/product/discovery/reference/r_DataCollDiscoWindowsComputers.html

So, you can check the table mention in the above link, you will have idea about where discovery populate the data for windows discovery.

Mark as correct, If you think this as helpful.

Hi ,

As we know that probes bring data from the target device and sensor

process the data and populate into the database.

Discovery works in four phases .

1.scanning : discovery finds which ports are open like 135 is open on window .

shazzam sensor matches this port with the protocol like wmi , ssh, snmp.

2. then shazzam launches the classification probes  (if port is 135 matches thjen it sends wmi classification probes ).

3. classification probes brings  class name of the device (if the device is window server then its class is computer ), operating system name, hostname , os version etc.

4.based on the class name and operating system name the device is classified.

5.after that the identification probes are launched which brings data like serial_no,serial_no_type, mac address, bios info ,ip address  etc.

6.based on above info a ci is identified  and updated this info into the table like if my operating system is window server 2008  then the info is populted into this table (cmdb_ci_win_server).

7. after that exploration probes are launched to get more info like no of processes  running, no of software 

installed , ram info, disk size, manufactorer info, the information of the application running on the device 

like mssql, tomcat (version etc ) these application info are stored on diff table based on their relationship.

for more detail please refer below documentr
